The Tecuamburro volcanic complex has a diverse history. Collapse of the ancestral Pleistocene Miraflores volcano created a large horseshoe-shaped caldera open to the east, producing an avalanche deposit that traveled across the Río los Esclavos (right). The modern Tecuamburro complex, consisting of four andesitic lava domes, was constructed within this scarp. The Laguna Ixpaco crater was created about 2900 years ago within the much larger Chupadero crater of Pleistocene age.
